Advanced Technology with 75 Years of Experience

Advanced 2 Stage-Diamond honing is used on all cylinder finishing and cylinder bore restorations, providing a well-engineered surface. U.S. Chrome’s Nickel Silicon Carbide Composite cylinder plating method outlasts and outperforms the competition and is superior to steel sleeving, resisting far more wear. Apply our durable NiCom coatings to wear-prone aluminum and steel cylinder sleeves to increase engine life and performance. At 600 Vickers (62-64 Rockwell C) hardness on average, our coatings are vastly superior to cast iron, most Asian OEM plating, and any knockoffs our competitors are trying to sell you. As long as your engine remains properly lubricated, your bores will never scuff or streak. Our NiCom coatings are engineered to withstand prolonged exposure up to 1200°F (540°C), meaning you can push your engine as hard as possible. Don’t let inferior plating chemistry rob your high-performance racing engine of precious horsepower and compression. OEM to overbore, U.S. Chrome’s custom designed 2 Stage-Diamond Plateau honing process makes the straightest, roundest cylinder bores with a diamond-hard surface for the best oil retention and lubricity possible!
